First Steps with OpenELEC on the Raspberry Pi 2
OpenELEC uses very little system resources for processor or memory. There's no need to use any special customization tips to get good performance with the RPi2. There's also no need to overclock the machine, reduce the resolution of videos, or use a different skin (although I really like the Amber skin).
